week 4

In this week we tackled in BST are how to enter in a confined space, Neil Robertson Stretcher and Army litter, and the different types of carries. (Examples of carries: Fireman’s Carry, Pack-Strap Carry, Chair Carry, One-Person Arm Carry, Two-Person Carry, and Two-Person Arm Carry.)

Sir Bosun first told us in how to enter in an confined space, First Get an Entry permit in order to start working in an confined space and this permit only last in 8 hours. Then check the oxygen level if it’s 21% you can go in the confined space without wearing a SCBA. Finally he told us the necessary equipments when working in a confined space is: Flash Light, First Aid, SCBA, and Life Lines.

Then after the lecture at 10:00H we went to the smoke house for practical in entering I a confined space there are two cadets one is the tender and the other one is the wearer. First the wearer will go in the confined space or enclosed space the he will contact the tender with a pull. One pull is are you ok, and two pulls is I’m going ahead. Three pulls is I’m going back, and four pulls is send help.

On Wednesday still in BST Sir Bosun told us about the Neil Robertson Stretcher and Army litter, and the different types of carries. The Neil Robertson Stretcher is designed to remove a casualty form confined space or enclose space. Because its design to carry the casualty vertically. And “the Army litter is collapsible, made of canvas, and supported by wooden or aluminum poles. They are used aboard ship only for mass casualty situations”

And finally he teach us the different types of carries, practically the fireman’s carry is the easiest way in carrying an casualty. The Pack-Strap Carry can be used to move a heavy casualty for some distance. Chair carry is when the casualty is sitting on a chair by two people.

In physics we tackled are the falling body and the projectile motion. The falling body is when the object was drop, thrown vertically upward. The projectile motion is when the object was thrown horizontally with high angle.
